To (ZZZ whom it may concern:

Be it known that l, FREDERICK H. MILLER,

a citizen of the United States. and aresident of the city of :Portland, county of Multe nomah, State of Oregon, have invented a certain new and useful Improvement in Machines for Melting lee-Cream Cones and the like or" which the following is a specification.

This invention relates to automatic machinery usecl in the manufacture of ice-cream cones, (leini-tasse cups. and other containers made of cake batter. The steps of such manufacture consist in placing the raw batter in baking ovens, baking the batter in the ovens, removing the baked containers from the ovens. and then recharging the ovens with raw better and. repeating the cycle of steps.

One of the main objects of invention is to proviole an improved machine for the manufacture of containers of the above mentioniecl type which embodies, among others the following features: a lower operating cost, a more convenient manner of operation, and a construction much simpler than the machines heretofore usecl. To this enci, in my machine. the baking ovens are arranged in batteries so that the caps-city of the machine may be increased or {iirninisheol by the addition or removal of one or more batteries of ovens. Furthermore, in order t bake a plurality of cones uniformly l orovide for 1 the heating of these ovens by electricity. Further features of my invention consist in the arrangement of an automatic control by means of which all of the movements of the machine are perfectly timed in relation to each other, 410 In the acconipenying Fig. 1 is diagrammatic side elevation of s port on of the machine, hein broken 4.

bracket 03, the pins f aid rod f carries a .stud pin f", which bears in the slot of the sector 6, and on the lower end of the rod is a cam roller f. Also vertcally reciprocable in the said frame members of each bracket (1 is a cylindrcal rod g. Said rod has fixed on it a block 9' in which is a horizontal slot adapted to act as a slideway for the stud pin 6'' of the sector 6. Also fixed on the rod 9 is a block 9 made with a cut-out portion 9 (see Fig. 2 On the upper end of the rod 9 is mounted one end of a cross beam h, in which the core elements z are supported. A third rod j, also vertically reciprocable in the shelves d d has on its lower end a cam roller j. The rod 7' is of square cross-section and bears'in the cut-out portion 9 of the block .9 By this means the rod 9 is held against rota,- tion. The rod j extends through a slot in the cross beam h, and has fixed. on it at a point between the shelves d (Z a cam plate In. The latter is made with two inclined slots 76 symmetrical with respect to'a center line. Cam rollers m fixed on the ends of the pivoted oven mold sections m bear in It is the vertical movement of the cam plate k that opens and closes the oven molds.

The mold sections m comprise aluminum matrices, backed b electric heating elements, the whole being suitably mounted in cast-iron cases m Said cases have fixed on their ends the cam rollers m. An integral part of the cases m are the longitudinally projecting legs m each having ,a transverse extension m*, the latter forming a convenient means for bolting onto the radius'arms n.

Directly beneath the center line of each oven, and bolted on to the frame members 0 are the shaft supports n. Said supports form bearings for two parallelrotatable shafts M. Bell cranks n are fixed on these shafts n and a link at connects adjacent legs of these bell-cranks. The other legs-are bolted to the radius arms n. The link connection n insures a symmetrical accurate movement of the mold sections relative to each other. See Figs. 5 and 7.

Longitudinal rails, 0, laid on cross-ties 0,

which are supported by brackets, 0 from the frame members 0, form a trackway upon which a car ;0 is capable of having a periodic and intermittent longitudinal motion forward the length of the machine under the baking ovens of the latter. The car 1) comprises the axles p, wheels p frame members 77 and cams q, 9 7", T The cams g g are in the same vertical plane with the cam roller f, and the cams 1" r are in the same vertical plane. with the cam rollers j. The cams q 1" are pivoted at g and .1 respectively, their counter-clockwise rotation being limited by the stops g, 7', while the cams g r are fixed in position. This car p also carries a batter tank 8 containing cake batter, with a dipper s therein adapted to be periodically lifted as the car is positioned under each oven so as to recharge the ovens with batter. The dipper s is provided with arms 8 vertically movable between guide rolls 8 on the ends of the tank. Lifting arms 8', pivoted on a shaft 3 at the rear of the car, have their forward ends slotted and said slot-s engage studs 8 projecting from the arms 8 The lifting arms at are connected by a transverse member 8 which projects down below the plane of the tops of the rails 0, and which is adapted to be operated on by the automatic means which periodi cally act so as, to elevate the dipper.

The cross beam h which supports the core elements 2' is made as follows: This beam is made in a channel form with the Sides widened at their middle portion for purposes of re-inforcement. A series of holes h are made in the center line of the beam, and bushings k are inserted in these holes. The bushings are of smaller diameter than the holes h,which allow a certain amount of displacement and collars h of larger diameter than the holes revent the bushings from falling out. he core elements 2' (see Figs. 4, 6 and 7) comprise an aluminum cone i made with a peripheral collar i An axial bore 2' is drilled in this cone for aportion of its length, and a piece of tubing 2', having its upper end threaded and adapted to be inserted through the bushing it, is firmly fixed on Said cone, the tubing 2" and the bore 5 being co-axial. In assembling, (see Figs. 4, 4, 4) acompression coil-spring i is slipped over the tubing i the latter is then inserted through the bushing b and a collar 2' is screwed on the threaded end of the tubing. This arrangement compresses the spring 2' so as to hold the cone relatively rigid, but at the same time allowing the cone to move axially against the expansive force of the spring i when sufiicient force is applied. The electric heating element 1, shown in Figs. 7, 7*, is then inserted in the bore of the tubing 2'', and when a circuit is passed through said heating element the cone 2" will become heated. The heating element is made as follows: A piece of tubing l is lined with mica l and a specially coiled resistance wire l is inserted in said tubing. The lower end of the'tubing is plugged up with an insulating medium Z and the tube 1s filled with insulating cement Z to prevent a possible short- Int) memos nected in series to themein circuit Wires the individual ovens being connected in muitiple to said main circuit wires.

The mold sections m contain the female die members of Which the cones 'i' are the mate members. The aluminum sections m have formed on their inner faces the filigreed heives m of the female die members The backs of these sections are recessed, shot asheet of mice m placed against the face of same.

This action closes the molds to their normal position. One of said mold sections is made with centering pins 2, and the other mold with a centering hole 3, adapted to receive said pin. This insures a return to e'xactposition. As soon as the molds m have been closed, as shown in the full lines of Fig. 6, the cams 9 will pass under the cam rollers f. This permits the cross beam h and thereby the core elements 71 to drop downward by gravity. It is essential that the batter be uniformly spread about the cores when seated in the molds, since such condition will insure even baking of the latter. In order to assure such result it is necessary that the cores; be centered in the molds. Such centering is effected by providing the tops of the female forms or mold sections 712 with centering pins 4 (see Figs. 6 and 7) preferably rounded at the top. These pins 4 are so positioned 1 relatively to the rims i of the cores as to bear against such rims and thus hold the cores centrally in the mold sections when seated therein. The weight of the core elementsi and cross beam h is sufiicient-to compress the batter & on the cone uniformly, but not suflicient to force it out of the form altogether.

It is to be noted that an interval elapses from the time that the core elements 2' drop by gravity until the cam 9 passes over the cam rollerf and forces down a trifle fur ther the core elements 71. This interval permits the batter to become, slightly set, so as to withstand the high pressure between the cones i and the female forms m. This last movement leaves all parts in the position shown in the full lines of Figs. 4, 5 andfi. Note that the final depression of the rod 7 causes the sector to rotate to the point where the stud pin e and the center of rotation of the sector are in a direct vertical line. In this way the rod 9 will be locked against upward movement until the sector 0 is rotated by the upward thrust of the rod f, the latter being caused' by the passage of the cam g beneath the cam roller f as previously described.

It has been found in practise that a certain amount of steam Wlll be formed when the batter begins to bake. I have provided for the escape of this steam by using the compression springs i, which allow the core elements to raise slightly under the steam pressure, and after the latter has been exhausted, the springs will force the cone downfirmly in-its seat once more. v

The passage of the car is so timed that the movements connected with thanperationof the ovens will be identically. periodic. As the car moves forward it will pass under the next baking oven where the action will be repeated. As the car moves back to initial position, the cams g and 1", being pivoted, will idle over the corresponding cam rolls f, j, and the ovens will not be interfered with in any way. The means for bringing the car back to initial position are not described in this specification, but this may be accomplished by opening the motor switch, releasing a clutch w, which engages the sprocket a with the shaft u, and thereupon pushing the car back by hand.
